Trouble eFiling State S Corp Return

I filed my Federal Return by mail but I need to file NJ S Corp return by eFile.  When I attempt to do so, I get an error message that indicated the business name must be linked to the Federal return.  The business name displayed on the NJ form is correct, but it is in RED like an override.  I suspect this is happening because I am not eFiling the federal return.  It says something about making the Federal return a PDF attachment but I can't figure out how to do so.
